In France February 2l, 1936 The present invention has for its object atool consisting of the.a combinationof several screwdrivers in 'orderthat it will serve to operate screws of diiferent sies, and chieiiyadapted for use as I atoolwhich can bereadily transportedin akitorasack,orcarriedi n.thepocket. l
